My sister-in-law gave me a set of dark chocolate polyhedral dice for Christmas 2012. I posted about them, along with a photo, back then, but I finally used them to play Dungeons & Dragons in February of 2013, and then I added their label to my collection.
BTW, my first roll with the twenty-sided die was an 18. So close to a critical. And then my party ate the dice, and they were pretty good! A little too sweet for 60% cacao, but they still had a rich chocolate flavor.
